error when installing on Debian Stable: This environment is externally managed

[github12101]

Followed readthedocs tutorial to install.

$ pip3 install .
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.

    See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

Set Up Python Virtual Environment Create a virtual environment and activate it: ex -

python3 -m venv electrumx-venv source electrumx-venv/bin/activate

Then , you can install dependencies without any error.

And add the paths in /etc/systemd/system/electrumx_GLC.service correctly. like this

ExecStart=/path/electrumx-venv/bin/python /home/user/electrumx/electrumx_server

sudo pip3 install . --break-system-packages should do the trick too
